Answer:
2. Hip bones
Explanation:
More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.
Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.
assuming that there are no answer choices, as you did not provide any, I shall say that the most likely result in the creation of a bunch of fossils would be a lot more oil, as the fossil fuel didn't get its name for nothing. there are other possibilities, but without the answer choices this is the best I could do. hope this helps!
They both have a cell membrane, mitochondria, cytoplasm, ad a nucleus. Hope this helped! :)
Answer:
In photosynthesis carbon dioxide is fixed and oxygen is released. In breathing, oxygen is consumed and carbon dioxide is released, releasing energy.
Explanation:
Explanation:
Cellulose, hemicellulose and lignin form structures called microfibrils, which are organized into macrofibrils that mediate structural stability in the plant cell wall.
The most important biological role of hemicelluloses is their contribution to strengthening the cell wall by interaction with cellulose and, in some walls, with lignin.
